I am quite frustrated, and would appreciate hearing any suggestions. It is matters, I am hooked up to a wired connection via ethernet, and to my TV via HDMI. I am not aware of any means of dropping back to a prior firmware release, not do I have any particular interest in running outdated firmware. When I picked up this replacement unit and installed it, initially scrolling was ok, but after I was prompted to install the firmware update (3/30/10, the one that gives it compatibility with Windows 7) the problem started. Now that it has happened with two sealed retail units, I am thinking it is not a defective unit but rather an issue. In prior Windows variations, you would require to click on on the sedentary screen (Firefox in this example) to be able to scroIl it.But in Windows 10, you can scroll the inactive window (Firefox right here) by simply hovering the mouse cursr over it nd moving mouse wheel or clicking arrow secrets on keyboard. Yesterday evening I purchased this item also at BB and returned it because of the same problem. I purchased this unit at Best Buy this morning. This same behavior takes place on the onscreen keyboard, which makes it almost impossible to use. The scrolling is so quick to that I have to time it just right (and it can take many tries) to get to select the right item. The only way to stop the scrolling is to press the Stop button (located just beneath the down arrow). When I press any of the four arrows on the remote, the cursor on screen rapidly and continuously scrolls through all visible menu items again and again without stopping.
